NCP134AMX090TCG ON Semiconductor

500 mA, Very Low Dropout Bias Rail CMOS Voltage Regulator NCP134 The NCP134 is a 500 mA VLDO equipped with NMOS pass transistor and a separate bias supply voltage (V ). The device BIAS www.onsemi.com provides very stable, accurate output voltage with low noise suitable T for space constrained, noise sensitive applications. In order to optimize performance for battery operated portable applications, the MARKING NCP134 features low I consumption. The XDFN4 1.2 mm x 1.2 mm Q DIAGRAM package is optimized for use in space constrained applications. 1 Features XXM XDFN4 Input Voltage Range: 0.8 V to 5.5 V CASE 711BC 1 Bias Voltage Range: 2.4 V to 5.5 V XX = Specific Device Code Fixed Voltage Versions Available M = Date Code Output Voltage Range: 0.8 V to 2.1 V (Fixed) 1.5% Accuracy over Temperature, 0.5% V 25C OUT UltraLow Dropout: Max. 150 mV at 500 mA, 1.1 V Output, 3.3 V PIN CONNECTIONS Bias, 85C Very Low Bias Input Current of Typ. 80 A IN43 EN Very Low Bias Input Current in Disable Mode: Typ. 0.5 A Logic Level Enable Input for ON/OFF Control GND Output Active Discharge Option Available 5 Stable with a 2.2 F Ceramic Capacitor OUT BIAS 12 Available in XDFN4 1.2 mm x 1.2 mm x 0.4 mm Package These Devices are PbFree, Halogen Free/BFR Free and are RoHS (Top View) Compliant Typical Applications Batterypowered Equipment ORDERING INFORMATION See detailed ordering, marking and shipping information on Smartphones, Tablets page 10 of this data sheet.
